How Gelco Products Fail - and How We Fix Them

• Gelco Multi-Flue caps in the 5/8-inch mesh series develop sagging lids on Chicago’s south-facing exposures after seven to ten summers. The heat-cycling between Lake Michigan’s humidity and inland dry spells fatigues the lid support brackets faster than in coastal or fully inland climates. We replace with OEM-grade brackets or upgrade to a heavier-gauge aftermarket hinge set, depending on flue configuration.
• Gelco single-flue stainless caps (Model 100 and 200 series) show base-seam separation where the mounting skirt meets the hood. The 200-series hoods in particular carry a lighter gauge that works fine in milder zones but can split at the seam weld after repeated freeze-thaw in Chicago winters. We either re-weld and seal the seam in place or recommend stepping up to a heavier single-flue cap if the flue tile condition allows.
• Gelco copper caps on vintage Hyde Park and Evanston-border homes pit at the base where acidic condensation collects, not from the copper itself failing but from the original installer omitting a proper drip edge. We fabricate a matching copper drip edge or replace the base section, preserving the patina homeowners paid for.
• Gelco crown wash coatings on masonry chimneys in Bucktown and Logan Square delaminate in sheets when applied over active efflorescence that was not addressed first. The coating itself is sound; the substrate was not prepped. We grind back to clean masonry, treat the efflorescence with a silane-siloxane blocker, then reapply the crown coating so it bonds.
• Gelco top-mount dampers integrated with cap assemblies seize in the closed position after winters with heavy ice dam runoff down the chimney face. The damper cable housing corrodes at the termination point. We replace the cable and housing with a marine-grade stainless assembly, reroute the drainage path, and test the damper through a full burn cycle before we leave.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers at (888) 289-6055, 24/7. We book a window that works, usually within 24 to 48 hours.
2. 2
   Level-2 camera inspection. Our technician arrives in uniform, runs a camera up the flue, and photographs the cap, crown, and flue top from inside and out. You see the photos. We give you a plain-English verdict: what is wrong, what caused it, and what it will cost to fix.
3. 3
   Parts decision. If your Gelco part is still in production, we source OEM. If it is discontinued - the early 1990s galvanized multi-flue line, for instance - we match with a quality aftermarket equivalent from our stock or from Copperfield or Famco, and we tell you exactly what we are using and why.
4. 4
   The repair. Most Gelco cap and crown jobs finish in one visit. We remove the failed component, address any underlying masonry or flashing issue, install the new cap or apply the crown coating, and seal all joints with high-temp silicone rated to the application.
5. 5
   Testing and documentation. We run water over the cap to check drainage, verify damper function if one is present, and photograph the completed work. You get a written report with photos and the 90-Day Done Right Promise.
6. 6
   Cleanup and follow-up. We haul away the old material. If anything is not right in the next 90 days, we come back. In writing, no arguing.
